The balsam twig aphid, Mindarus abietinus Koch (Hemiptera: Aphididae), is one of the most important pests of balsam fir (Abies balsamea (Linnaeus) Miller; Pinaceae) grown as Christmas trees in eastern North America. Aphid feeding on the current-year shoots results in needle distortion and shoots stunting, which reduces the aesthetic value of balsam fir trees and can have substantial economic impact. Syrphidae (Diptera) fly predators attacking this aphid are poorly known. We identified four species attacking the balsam twig aphid. Syrphus torvus Osten Sacken (Diptera: Syrphidae) was the most abundant species followed by Eupeodes lapponicus (Zetterstedt) (Diptera: Syrphidae) and Eupeodes americanus (Wiedemann) (Diptera: Syrphidae). We described the seasonal natural history of the two most abundant syrphids feeding on this aphid and we studied their synchrony with their prey. Syrphid larval density on balsam fir shoots increased rapidly and closely followed density of the balsam twig aphid. We also reported heavy parasitism of syrphid pupae by two Hymenoptera on tree foliage but lower parasitism on pupae in the soil under trees. Several cases of multiple parasitism and hyperparasitism were observed in syrphid pupae under trees. Abundance of predaceous syrphid species was higher in untreated balsam fir plantations compared with treated plantations. More research is needed to understand the role and the impact of these predators on balsam twig aphid population dynamics.

Species of the genus Tinotus Sharp of America north of Mexico are reviewed. Five species are recognized: T. caviceps Casey, T. imbricatus Casey, T. morion (Gravenhorst), T. parvicornis Casey, and T. trisectus Casey. The genus Tinotus is recorded from Canada for the first time and is represented in the country by two previously unrecorded species: T. morion (Gravenhorst), introduced from the Palearctic region, and T. caviceps Casey, described from Nevada and subsequently reported from California, Idaho, Indiana, Iowa, and Montana. Tinotus morion was previously listed in North America from Connecticut and Nevada (unverified records), but until now it was unknown from Canada. Here it is reported as new for New Brunswick, Quebec, Ontario, Alberta, and British Columbia. Tinotus caviceps is found for the first time in southern Quebec where it probably reaches its northern distribution limit. The following synonymies are established, with the first names being valid: T. caviceps Casey (= T. pallidus Casey), T. imbricatus Casey (= T. amplus Notman, T. brunnipes Notman), T. parvicornis Casey (= T. planulus Notman), and T. trisectus Casey (= T. binarius Casey, T. brunneus Casey, and T. lateralis Notman). A new lectotype is designated for T. brunnipes Notman. The lectotype specimens have been dissected and their genital features illustrated. Diagnoses, illustrations, and a key to identify species from America north of Mexico are provided.

The Canadian species of the genus Placusa Erichson are reviewed. Eight species are recorded, of which four constitute new Canadian records (P. despecta Erichson, P. incompleta Sjöberg, P. petulans Casey, and P. vaga Casey) and two are new to science (P. pseudosuecica Klimaszewski sp.nov., and P. canadensis Klimaszewski sp.nov.). Placusa turbata Casey, one of the two species previously recorded from British Columbia, is here considered a synonym of P. tachyporoides (Waltl) and is reported for the first time from eastern Canada (New Brunswick, Ontario, Quebec). New data are provided on the systematics, distribution, bionomics, and relationships of selected North American species. A key to the species occurring in Canada is presented with illustrations of the median lobe of the aedeagus, spermatheca, male tergite 8, antennae, and outline drawings of the head and adult forebody for each species. Selected Palearctic species are also illustrated for easy comparison with the closely related Nearctic species. The Canadian distribution is presented on contour maps, and world distribution is discussed for all species. The following lectotypes are designated for the Nearctic species which were described from more than one specimen without former holotype designation: Casey (1893, 1911): P. frosti, P. strata, P. tacomae, P. turbata; Erichson (1840): P. despecta; and Sachse (1852): Oxypoda minuta Sachse. Oxypoda minuta is transferred to the genus Placusa and newly synonymized with P. despecta Erichson (1840).

A review of the Nearctic genera and Canadian and Alaskan species of the Ocalea group is presented. Ten genera are treated, with five erected as new: Alfocalea Klimaszewski gen. nov. (type species: A. montana Klimaszewski sp. nov.), Betocalea Klimaszewski gen. nov. (type species: B. pacifica Klimaszewski sp. nov.), Gennadota Casey (reinstated), Longipeltina Bernhauer, Megocalea Klimaszewski gen. nov. (type species: M. lemieuxi Klimaszewski sp. nov.), Metocalea Klimaszewski gen. nov. (type species: M. lindgreni Klimaszewski sp. nov.), Neoisoglossa (Casey) (nomen novum), Neothetalia Klimaszewski gen. nov. (type species: N. nimia (Casey)), Ocalea Erichson (restricted definition), and Parocalea Bernhauer. Twenty-four species of the Ocalea group are here recognized in the Nearctic region, fourteen of which occur in Canada. Six new species are described from western Canada and Alaska: Neothetalia smetanai Klimaszewski sp. nov. (Canada: British Columbia), Neothetalia canadiana Klimaszewski sp. nov. (Canada: British Columbia, Yukon Territory; United States: Alaska), Betocalea pacifica (Canada: British Columbia), Alfocalea montana (Canada: Alberta, British Columbia), Metocalea lindgreni (Canada: British Columbia), and Megocalea lemieuxi (Canada: British Columbia). The first record of Neoisoglossa agnita (Casey) in Alberta is provided. Two nominal species, Atheta (Athetalia) bicarniceps Casey (= Neoisoglossa) and Isoglossa grandicollis (Casey) (= Neoisoglossa), are here synonymized with Neoisoglossa arcuata (Casey). Aleochara pallitarsis Kirby has been transferred to the genus Neothetalia and is newly recorded from Alaska and British Columbia. Ocalea columbiana Klimaszewski has been transferred to Neothetalia and is newly recorded from Alaska. Neothetalia pallitarsis was formerly recorded from an unknown locality in North America and Neothetalia columbiana from the Carmanah Valley on Vancouver Island. Neothetalia nimia is newly recorded from Alaska. A new generic classification is proposed to accommodate species of the Nearctic Ocalea group. New data are provided on the systematics, relationships, bionomics, and distribution of the Nearctic species and genera of America north of Mexico. Diagnoses, colour images of entire bodies, and line illustrations of genital features are provided for those Canadian and Alaskan species that were not formerly illustrated, and their collection localities are plotted on maps. A key to Nearctic genera of the Ocalea group and the species occurring in Canada and Alaska is presented. The lectotypes have been designated for the following nominal species because the original series consisted of syntypes or represented mixed species or both sexes but with males bearing a better diagnostic set of characters: Aleochara picata Stephens (= Ocalea), Atheta (Athetalia) bicarniceps, Atheta (Athetalia) nimia Casey (= Neothetalia), Atheta (Athetalia) repensa Casey (= Neoisoglossa), Isoglossa arcuata Casey (= Neoisoglossa), Ocalea agnita Casey (= Neoisoglossa), Ocalea franciscana Casey (= Neoisoglossa), Ocalea fusca Fenyes (= Neoisoglossa), Ocalea grandicollis Casey (= Neoisoglossa), Pyroglossa grossa Bernhauer, Rheobioma disjuncta Casey (= Neoisoglossa), Rheobioma marcida Casey (= Neoisoglossa), and Rheobioma terrena Casey (= Neoisoglossa).

Eight additional adventive aleocharine beetles, native to the Palaearctic region, are reported from Canada, five of them for the first time. They belong to three tribes: Crataraea suturalis (Mannerheim) (Nova Scotia, Saskatchewan, British Columbia) and “Meotica pallens (Redtenbacher)” (Ontario, British Columbia) belong to Oxypodini; Atheta (Chaetida) longicornis (Gravenhorst) (Nova Scotia, Quebec), Atheta (Thinobaena) vestita (Gravenhorst) (New Brunswick), Dalotia coriaria (Kraatz) (Alberta), Dinaraea angustula (Gyllenhal) (Nova Scotia, Prince Edward Island, Quebec, Alberta), and Nehemitropia lividipennis (Mannerheim) (New Brunswick, Nova Scotia, Prince Edward Island, Quebec, Ontario) belong to Athetini; and Homalota plana (Gyllenhal) (Nova Scotia, New Brunswick) belongs to Homalotini. These species have likely been introduced into Canada from Europe by various anthropogenic activities, and their bionomics and possible modes of introduction are discussed. For each species, a short diagnosis and habitus and genital images are provided to assist with identification. The habitus and genital images are presented here for the first time for these species in North America. New United States records are not included in the abstract.

Rove beetle species and their pitfall trap abundance were studied in red spruce (Picea rubens Sarg.; Pinaceae) stands in the Acadia Research Forest, New Brunswick, Canada, in 1999. The study yielded over 5000 specimens representing 134 species in 11 subfamilies of Staphylinidae. Of these, 58 species represent new distribution records for New Brunswick (NPR), including 15 new distribution records for Canada (NCR), 6 new species, and 4 synonyms, as follows: Omaliinae, 3 species; Proteininae, Proteinus pseudothomasi Klimaszewski sp. nov. (NCR, NPR) and P. acadiensis Klimaszewski sp. nov. (NCR, NPR); Tachyporinae, 3 species; Trichophyinae, 1 species; Aleocharinae, 33 species, including Atheta capsularis Klimaszewski sp. nov., A. brunswickensis Klimaszewski sp. nov., A. pseudocrenuliventris Klimaszewski sp. nov., Oxypoda lacustris Casey (NPR) [= O. bradorensis Lohse syn. nov., O. egestosa Casey syn. nov., O. lassula Casey syn. nov., and O. optiva Casey syn. nov.], and Pella gesneri Klimaszewski sp. nov.; Oxytelinae, 3 species; Paederinae, 3 species; and Staphylininae, 10 species. The new species or known species representing new records for Canada are presented here with a short diagnosis, habitus images, and genital illustrations to help with identification. The habitus images and most genital illustrations are presented here for the first time for these species.

Rove beetle assemblages from forest dominated by yellow birch (Betula alleghaniensis Britt. (Betulaceae)) at two sites in southeastern Quebec were characterized in terms of composition, diversity, and relative abundance. In total, 143 species were collected over two seasons (June–August of 1999 and 2000). In the pretreatment year (1999), 88 species were found in uncut stands. In the post-treatment year, 116 species were found in treated (by patch harvesting and ground scarification) and control plots combined. Sixty-one species were common to the two sites, 27 species captured in the 1999 season were not recaptured in the 2000 season, and 55 additional species were captured in 2000. There are 23 new distribution records for Quebec, and one species, Atheta (Dimetrota) pseudomodesta Klimaszewski, sp. nov., is described. New bionomics data on relative abundance, seasonality, and the utility of different trapping methods are presented. Assemblage composition is compared with that of a red spruce (Picea rubens Sarg. (Pinaceae)) forest in New Brunswick.

Three species of Telenomus Haliday are egg parasitoids of the hemlock looper, Lambdina fiscellaria (Guenée), in Canada. Telenomus coloradensis Crawford and Telenomus droozi Muesebeck are redescribed and Telenomus flavotibiaesp.nov. is described and illustrated from material collected in Quebec. Telenomus coloradensis was found to be the predominant egg parasite, followed by T. droozi. Telenomus flavotibiae was found to be an uncommon parasite of hemlock looper eggs. All three species are recorded from Newfoundland to British Columbia. Keys to species of Telenomus associated with the hemlock looper, including two closely related species previously confused in the literature, are also given.

A revision of the Canadian species of the genus Silusa Erichson is presented. In this contribution, we treat six species recently discovered in Canada, one of which is a new species from Alberta, Silusa langori Klimaszewski sp. nov. The distribution records for two species are greatly expanded. Silusa californica Bernhauer is now known from Alaska, Minnesota, Alberta, Quebec, New Brunswick, and Nova Scotia (previous records: British Columbia, California). Silusa vesperis Casey is now known from Washington and British Columbia (previous record: California). For two other species, there are first records for Canada and one new United States state record. Silusa alternans Sachse is now known from Quebec, New Brunswick, Nova Scotia, and New Hampshire (previous records: Georgia, New York), and Silusa densa Fenyes is now known from Alberta (previous record: California). Silusa valens Casey is here considered as a synonym of S. alternans. Silusa rutilans Casey and S. modica Casey are confirmed to belong to Leptusa Kraatz, and both are here considered as new synonyms of Leptusa canonica Casey. Silusa gracilis Sachse and S. nanula Casey are also confirmed to belong to the genus Leptusa. The following lectotypes are newly designated for species described on the basis of syntypes: S. alternans Sachse and S. californica Bernhauer. New data are provided on the systematics, relationships, bionomics, and distribution for all Nearctic species of America north of Mexico. Diagnoses and illustrations of external and genital features are provided for all species, and the distribution of each is discussed and shown on maps. A key to the species occurring in Canada is presented.

Monitoring the abundance of green turtles (Chelonia mydas) is necessary to assess population trends and risks of collapse. This note presents a study aimed at comparing three techniques for the direct estimation of green turtle numbers in their foraging habitats (seagrass beds and reef flats). The experiment was carried out at Mayotte Island, Western Indian Ocean. The techniques involved were surveys by snorkel, and aerial surveys using a microlight aircraft and a paramotor. Each technique had shortcomings and advantages. While each technique provided estimations of turtle numbers only surveys by snorkel permitted identification of species and sex, whenever visibility and turtle behaviour permitted. Along the shorelines, and over foraging areas, the paramotor was found to be most suitable for direct estimations of turtle numbers. The major advantage of this technique lied in its capability to obtain a synoptic snapshot of turtle distribution over foraging areas. Linear surveys from a microlight aircraft are better suited to monitor foraging areas located further away from the shore.

The levels of drought tolerance and nucleotide polymorphism at the CBF4 locus were examined in a world-wide sample of 17 core accessions of Arabidopsis thaliana. The results showed that different accessions exhibited considerable differences in adaptation to drought stress. Compared with Columbia accession, the frequency of nucleotide polymorphism at the CBF4 locus of 25av, 203av and 244av accessions, including single nucleotide polymorphism (SNP) and insertion/deletion (Indel), was high, on average 1 SNP per 35.8 bp and 1 Indel per 143 bp. No significance in all regions of Tajima's D test indicated that the neutral mutation hypothesis could explain the nucleotide polymorphism in this CBF4 gene region. The higher polymorphism was the result of purification selection. Nucleotide polymorphism in the non-coding region was three times higher than in the coding region. This might indicate a recent relaxation of selection pressures on the non-coding region of CBF4 gene. In the coding region of CBF4, SNP frequency was 1 SNP per 96.4 bp and one non-synonymous mutation was detected from 25av, 203av and 244av accessions: the amino acid variation gly↔val at position 205, caused by the nucleotide variation G↔T at position 1034 (corresponding to the nucleotide at position 19 696 of GenBank accession no. AB015478 as 1). Furthermore, four differential SNPs were discovered in haplotype 6 constituted by 203av, one of them located in the 3′ non-coding region (A↔C at position 1106) and the others in the 5′ non-coding region (A↔G, A↔C and G↔A at positions 27, 129 and 171, respectively). The drought tolerance assay indicated that accession 203av was the best at tolerating water deficiency. We propose that haplotype 6 is consistent with its drought tolerance.
